New Delhi, May 5: A recent study has uncovered three shared brain abnormalities that are common across insomnia, anxiety, and depression. One of the key findings is a smaller thalamus, a brain region involved in attention and memory, which has been linked to cognitive difficulties in individuals suffering from these conditions.
The study also identified two additional abnormalities: weakened connectivity between brain regions, which impairs communication across different areas of the brain, and a reduction in the size of the cerebral cortex—an area responsible for higher cognitive functions such as memory and language. This cortical shrinkage may contribute to difficulties in processing information and expressing thoughts.
Insomnia, characterized by trouble falling or staying asleep, has long been associated with an increased risk of mental health disorders, including anxiety and depression. The findings suggest that disrupted sleep could contribute to, or even exacerbate, these conditions by affecting brain structure and function.
These insights underscore the importance of early diagnosis and intervention for sleep disorders, which may help reduce the likelihood of developing anxiety, depression, and other related mental health issues.
